CIRCUIT-CLOSER.

SPECIFICATION forming part of Letters Patent No. 727,064, dated May 5, 1903. Appnmia fired January 2. 1903. V'si-.rial No. 137,501. (No model.)

tongue is thrown, the object of the inventionY being the production of simply-constructed means capable of attachment to the ordinary trolley-wheel and connections and operating in a reliable manner regardless of inclement weather conditions to close the circuit in which the magnet is located.

The nature of the invention will be readily comprehended, reference being had to the following detailed description and to the accompanying drawings, illustrating the invention in its preferred form, it being understood that various modifications may be made therein without departing from the spirit of the invention as dened by the claims.

In the drawings, Figure 1 is an elevation of a circuit-closer embodying the invention. Fig. 2 is a vertical transverse sectional view. Fig. 3 is a perspective view of a modification.

Referring to the drawings by numerals, 1 denotes the trolley-pole, having at its upper end arms 2 2, in which are bearings for the shaft 3 of the trolley-wheel 4. The feed-wire 5 is supported in the usual manner from an insulating-block 6, which in turn is supported by wires 7 7, one or bothof which lead to the switch-throwing magnet. (Not shown.)

S S designate rings or disks which flankA the trolley-wheel andare insulated therefrom by interposed rings or disks 9 9, of insulating material.

l0 10 are yielding contact-brushes carried by and insulated from the trolley-pole and from which lead circuit-wires 11 11, in which are located circuit-closers, such as push-buttons located on the car, the contacts 10 having a yielding engagement with the disks 8, 5o and said disks are also yieldingly engaged by contacts 12 12, pivoted to the block 6, which,

as stated, forms the support for the trolleywire. The contacts 12 by pivotal connection with the block are acted upon by gravity to engage the disks 8.

In Fig. 3 is shown a modified construction by which a prolonged engagement is made between the upper contacts and the disks 8.

A number of blocks 6 are suitably supported 6o and Vpivotally secured to the blocks, and depending therefrom are arms 14 14, to the lower ends of which are secured contact-bars 15 15, which yieldingly engage the disks Sas the trolley-wheel passes between them. The bars 15 15 may be made to have any desired length. Surmounting the structure is a hood 16, which extends beyond the ends of the bars. The circuit-wires 7, or one of them, lead from the contacts 12 to the coils of the magnets. 7o The parts are surmounted by a hood 13, supported from the block 6 and serving to protect the contacts from snow and ice, which would tend to clog their action. The circuitcloser being manipulated by the operator on 'the car, a circuit is established with the mo.-

.tor feed-wire through Wire 11, contact 10, disk S, contact 12, wire 7, and the magnet.

Obviously in the case of right and left hand side tracks separate switch-throwing mech- 8o anisms including magnets will be provided and will be controlled through the right and left hand wires 7 7, above described. There will also be on the car right and left hand push-buttons, either one of which is manipulated by the operator, dependent upon the direction the car is to leave the main track.

I claim as my invention- 1. In a circuit-closing mechanism', an insulated trolley-wire support, a trolley-wheel 9o anked by insulated disks, contacts in engagement with the disks and connected-with a controllable circuit on the car, and terminal contacts on said support engaging said disks.

2. In a circuit-closing mechanism, an insulated trolley-wire support, a trolley-wheel In testimony whereof I affix my signature flanked by insulated disks, brushes in conn presence of two Witnesses. tact with the disks and connected with a controllable circuit 0n the car, gravity terminal 5 contacts pivoted to said support and engag- Witnesses:
